Introduction

Three-dimensional crossing-shock-wave and turbulent boundary-layer interactions can generate intense wall heat flux rates, high pressure levels, and large-scale flow separations on high-speed vehicle surfaces. To reproduce such complex flow physics, simple configurations, such as single-sharp fin and double-sharp fin mounted on a flat plate, were adopted in previous investigations. Review papers by Knight et al. [1] and Zheltovodov [2] provided summary of current state-of-the-art of research advancements in this field. Recently, Yao et al. [3] carried out numerical simulation of symmetric double fin configurations of 7°×7°, 11°×11°, and 15°×15° wedge angles. Results of surface static pressure distributions were found in good agreement with wind tunnel experiments [4] and other numerical simulations [5] but heat flux coefficient distribution differed from experimental data at the 15°×15° case. In this work, an additional configuration of 19°×19° case is introduced to investigate flow topology due to increased shock-viscous interaction strength. The predicted flow field will be compared qualitatively with available experiments [6, 7] and other relevant numerical studies [7, 8].
